Subject: [PATCH v24 13/24] selftests/x86: Recurse into subdirectories
Date: Sat, 30 Nov 2019 01:13:15 +0200
Message-ID: <20191129231326.18076-14-jarkko.sakkinen@linux.intel.com> (raw)
In-Reply-To: <20191129231326.18076-1-jarkko.sakkinen@linux.intel.com>

Recurse into a list of subdirectories defined by SUBDIRS when running
x86 selftests. Override run_tests, install, emit_tests and clean
targets to implement this behaviour.

A possible alternative would be to add "x86/sgx" to TARGETS. However,
this would be problematic because detecting 64-bit build would have
to duplicated.

The implementation is derived from the makefiles of powerpc and sparc64
selftests.
